'BASE-BURNING HEATING-STOVE.

To all whom it may concern:

Be it known that I, WILLIAM T. Ensrns, a citizen of the United States, residing at Graston, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Base-Burning Heating-Stoves, of which the following is a speciication.

My invention relates to base-burning heatingsstoves.

The objects of the invention are to -provide a base burning heating stove adapted for burning soft, or hard coal or wood; to provide a stove in which the products of combustion are caused to travel from above the ire pot down along the front of the stove around a cold air dome in the base, and thence up along the back to the smoke outlet, to provide a stove in which upon removing the top a framework forming the flues, lire pot support and ash chamber may be removed as a whole; to provide the base under the ash pit with a central cold air dome or cylinder open at its bottom and vclosed at its top by the bottom of the ash pit, thus forming in connection with the surrounding casing an annular flue connecting the front and rear flues formed between the vertical front and rear sides of the frame and the said casing; to provide a removable magazine for use with hard coal but which may be removed when soft coal or wood are to be used; to provide a foraminated elliptical fire pot with its ends next to two doors so that the burning fuel may be readily stoked through the openings from either side; to provide such a stove which shall be simple in construction, easy to assemble and repair, inexpensive to manufacture and durable. These objects I accomplish by the construction shown in the accompanying drawings, in which- Figure l is a central vertical sectional view through a stove provided with my improvements; Fig. 2 is a similar view in a plane at right angles to Fig. l; Fig. 3 is a perspective of the removable frame; Fig. l is a perspective of the lire pot; Fig. 5 is a like view of the grate supporting bar and grate.

A, designates the cylindrical metal casing preferably of sheet metal and open at both enc s.

B, is the base provided with a circular, centrally apertured raised portion B', closely tting the lower open end of the casing and Specification of Letters Patent.

provided above at its apertured portion with an open ended sleeve or collar B2 forming a cold air dome around which an annular space or flue b2 is provided within the lower end of the casing.

C, is a removable frame, the parts of which may be separately formed and secured together or they may be formed as a single casting. This frame C comprises two parallel vertical side walls C C2, corner posts C3, rounded to snugly it the interior of the casing, a horizontal middle partition C6 having an elliptical opening and forming a rest or support for an elliptical fire pot D. The bottom of the frame C, forms the floor of the ash pit, closes the top of the cold air dome B2 and also closes the top of the annular base flue b2 at the opposite sides of the casing. Between the vertical sides C C2 of the frame C, and the front and rear sides of the casing A, are spaces reaching from the top of the casing to the bottom and forming flues 3, b4, which open at their lower ends into the annular base flue b2. The front wall or side C, of the frame C, is provided above the fire pot with a down-draft opening c leading into the flue b3 while the wall C2 is provided directly opposite the opening c with a direct draft opening o2. This opening c2 is opposite the smoke outlet A in the rear side of the upper portion of the casing A and is provided with a damper C9, sliding in ways 09, c, and having an operating rod C10, extending through the casing A. The upper ends ofthe side walls C, G2, are connected by cross-pieces 013 014.

The top E, of the stove is circular and fits within and closes the top of the casing A and has on its lower sides parallel ribs e, which receive the upper ends of the walls or partitions C C2 and this top closes the upper ends of the flues b3 b4. At its front and rear the top E, is provided with openings c c2 communicating with the upper ends of the flues 3, b4, and closed by suitable closures c3, c4, mounted on the upper side of the top.

Centrally of the top isa rabbeted elliptical opening c5, adapted to removably receive the elliptical, tapered magazine F, having a Bange around its upper end to seat in the said opening. The opening 65 is closed by an elliptical lid E, having a central opening closed by a smaller lid E2 having a cross-bar eG pivoted to its under side and engaging with its ends the under stirring the fire, &c.

'down-draft fines, &c. ris secured in place and the stove is ready for "use,A V If hard coal is.to be` used the magazine will' be'inserted or it will be left outA side of the main lid E. The lid E closes the top of the stove and also the upper end of the magazine when it is used.

Both sides of the frame C, at right angles to the walls C C2 are open and both sides of the casing A, above and below the fire pot rest C6 are provided with doors Gr, G, having draft slides; the upper doors G, open into the combustion chamber above the fire pot while the lower doors G, open into the ash pit. Below the doors G are small doors G2, through which the base Hue 62 may be cleaned. The vertical fines b3 b, may be cleaned through the top openings e e2.

The lire pot D, is elliptical in cross-section and tapers from top to its circular lower end. It is removable from t-he rest or support CG. Vithin the lower end of the fire pot are removably secured two heavy iron bars D, which cross each other and serve to protect the shaking grate D2 from injury by heavy lumps of coal. This grate D2 is pivoted centrally to the middle portions of the bars D by a bolt (Z, and its lower side has two apertured lugs (Z2 (Z2 into lwhich the end of a poker, may be inserted for shaking the grate. The fire pot D, is a casting provided with a large number of openings through which a poker may be inserted from either side of the stove for The shape ofthe lire pot permits of the ready removal of clinkers, &c.

' Any suitable ash pan D4 may be placed in the ash pit and it may be removed through either door Gr. .The draft slides in the doors G, G', operate in the usual around the base fine b2, thence up through Hue bt, to the smoke outlet. The cold air dome B2, affords considerable radiating surface at the base of the stove and also protects the floor of the room from receiving an injurious amount of heat. By my lconstruction the front of the stove is highly heated before the heated products of combustion pass to the back of the stove to heat it and the greatest amount of surface heated.

The parts are readily assembled, the body 4or casing A, being first secured to the base 'B, then the frame C, is let down into the casing to divide it into its several parts of combustion chamber, ire pot rest, ash pit, After this the top where other fuel is to be employed. The fuel used may, therefore, be changed at any i time without otherwise changing the stove.

The construction illustrated may be varied without depart-ing from the scope of my invention.y
